HENRY O. LIMA, OF STAMFORD, CONNECTICUT, ASIGNOB, BY HEBNE ASSIGNMENTS,TO AT! BALE! OOBIORATION, OF YORK; N. Y A CORPORATION 01' NEW YORKREFUSE COLLECTOR Application filed April 11, 1925, Serial No. 22,858.Renewed December 5. 1928.

This invention relates to an improvement in an ash or garbage collectoror similar traveling machine, of the kind wherein a car or bucket ishoisted up a track on the side of a receptacle body on the vehicle toelevate and dump therein the refuse which is taken up as the machinemakes its rounds. The object of the invention is to provide certainnovel features and combinations,.making for increased efficiency,steadiness and safety of operation, and simplicity of construction, in amachine of this character.

To this end, my invention consists, primarily, in providing a novel-typeof side loading trough, in place of the usual car or bucket,--novelmeans for raising, emptying, and lowering the trough,-novel constructionof the cargo-body, whereby the same is made unusually dust-proof andsanitary,-

and novel means for dumping the load from said cargo-body at the dumpinggrounds.

In the accompanying drawings forming a part hereof Fig. 1 is a sideelevation of a motor truck vehicle embodying the invention, looking atthe side which carries the track, showing the trough or car in receivingposition at the foot of the track;

Fig. 2 is a side elevation, looking at the opposite side of the vehicle,showing the body tilted for dumping and the trough in its upper positionbeneath the hood;

Fig. 3 is a vertical transverse section taken in front of the body,showing the trough at the foot of the track and the reversible gearthrough which the trough is operated in neutral position;

Fig. 4 is a central vertical transverse section through the body,showing the trough or i car in its upper or dumping position, where itis retained bythe curvature of the track; I

Fig. 5 is an elevation on a larger scale of the reversible gear anddrive for the trough,

showing the gear in mesh'jor operating the car in one direction, whichfor illustration may be assumed to be the lowering operation;

Fi 6' is a similar view showing the re-v versi 1e gear in the otherdriving condition,

' Fig. 7 is an enlarged sectional view taken in the plane of the drumshaft, showing an embodiment of means for automatically throwing off thepower when the car reaches dumping position at the top and again when itreaches the foot of the track.

The drawings illustrate a motor truck vehicle embodying my invention,the chassis or frame of which is marked 2. A capacious enclosedreceptacle or cargo body 3 is tiltably mounted on this chassis, so thatit can be tilted from thechassis for discharging the load when thevehicle has completed a round of collections and has proceeded to aplace of disposal. As illustrated in Fig. 2, the body is hinged to thechassis at the rear on a transverse axis 4, and a suitable power'hoist 5is provided for tilting the body upwardly from the chassis. This powerhoist is operated through one of a pair of control levers 6 in thedrivers cab 7 this lever operating through a suitable connection 8 tocouple the hoist 5 with a gear wheel 9 (see Figure 3),

forming one of a suitable arrangement of gear wheels 10in thetransmission case 11, which are driven from the transmission shaft 12 ofthe vehicle when the vehicle clutch is in engagement and thetransmission gear shift lever 13 is in neutral.

.Thetop of the body is covered over, leaving, however, a longitudinallyextendingreceiving opening 14, which is overhun at one side by a hood15. A track compose of-two channel track members 16, attached to thetiltable body by brackets .17, extends up one side of the body from nearthe street level, over the top of the body, for the purpose of guiding acar or trough 18 to dump its contents through the opening 14. The trough18 extends approximately the length of the of. which turns downwardtoward, and pref-' erably into, the side of the opening 14 in front ofthe hood 15.

When the trough. is raised, the wheels or vertical sections of the trackmembers 16 onto the arched curve 20, causing the trough to tiltgradually from an upright position to a horizontal position, at whichdumping commences, and then causing the trough to travel down thefarther slope of the curve so that the trough tilts increasingly as itadvances, causing its contents to -be delivered into the body in aneffective manner. When the trough reaches the final dumping positionseen in Fig. 4, it is retained against return to the foot of the trackby reason of the fact that the wheels 19 must be raised over the curvebefore the trough can again be lowered.

The downturned upper ends of the track channels are preferably closed,as shown at 22, to provide a support for the trough in the position ofFig. 4, which is the position which it occupies 'when the vehicletravels.

In this position the trough enters within the hood 15 and substantiallycloses the opening. Stops 23 at the ends of a cross-piece 24, connectingthe lower ends of the track members, support the trough in its loweredposition.

It will be readily understood that, by having a capacious trough ofsubstantially the length of the cargo-body, and having a hoodedreceiving opening in the to of said body,

adapted to receive the beak o the trough, as

shown in Figure 4, the escape of any appreciable quantity of dust,cinders, or particles of refuse into the atmosphere, during the passageof the load from the trough into the body, will be prevented. As theload will have become evenly distributedin the interior of the troughduring its ascent, it will readily distribute itself evenly in droppinginto the cargo body. When the final load has thus been transferred ihtothe cargo-body, the inverted trough will stay on top of the body andserving to make, with the hood, a complete closure of the receivingopening during transportation. The many advantages of the constructionwill be apparent to all persons familiar with the handling of ashes,garbage, and other refuse in transit.

The trough is raised and carried over the top curve of the track by apair of cables 25.

' are guide pulleys 30 on the curved upper portions of the trackmembers, thence pass outside of the ends of the hood 15 toguide pulleys31 on theupper part of the body, beyond the hood, whence they passdownward to drums 32 on a shaft 33. This shaft is mounted rotatably inbearings 34 beneath the lower longiguide: members -19 pass from thestraight" tudi'nal corner portion of the tiltable body, at the sideremote from the track 16, where the support and draft are advantageous,and t where, also, the shaft and drums are protected by the overhang ofthe body. The other cables 26 pass from the arms 27 beneath guide tionalguide pulleys 38 mounted on vertical axes on the under part of the bodyguide the cables 26 in their transverse course. In the operation of thetrough the cables of one set wind up on their drums while the cables ofthe other set unwind, and vice-versa.

The cable hoist for the car is operated from another gear wheel orpinion 9, adapted to be driven from the main transmission shaft 12through the gearing ws When.the vehicle clutch is in and thetransmission gear shift lever 13 is in neutral, the pinion 9 may becoupled with the drive by one of the pair of control levers 6 actingthrbugh suitable connections 8. The pinion 9 is positioned to be engagedwhen the tiltable body is down on the chassis by either one of a pair ofmeshing gear wheels 39, 39 carried by a shifter 40, which is pivoted at41 to a bracket 42 on the under part of the body. When the shifter is inthe extreme position shown in Fig. 5, the gear wheel 39 will mesh withthe pinion 9, while in the other extreme position of Fig. 6 it is thewheel 39 which meshes with the pinion. In the neutral or mid positionseen in Fig. 3, neither of the wheels 39, 39 meshes with the inion, andconsequently the trough hoist wi not be operated in either direction.

A sprocket wheel pinion 43 which is united with the gear wheel 39carries a sprocket chain 44, which passes around a sprocket wheel 45 ona shaft 46 in a casing 47 securedto the body. A toothed pinion 48 on theshaft 46 meshes a gearwheel 49 fixed to the drum shaft 33. .When thehandle 50 of the reversible gear is moved to the position seen in Fig.6, the drum shaft will be driven in one direction, which may be thedirection to wind up on the cables 25 and pay out the cables 26, thuscausin the car to rise from the lower end of the trac over the top ofthe body and dump. When the parts are in the osition of Fig. 5, thedrums will be rotate, in the reverse direction, so that, for example,the cables 26 will be wound up on their drums matic throw-off isoperated from the rotatable shaft 33, on-the forward end of which is ascrew 51. On this screw is a traversing member 52, in the nature of anut, which is connected with the lever 50 by a link bar 53 connected at54 to the said lever and eccentrically pivoted at 55 to the member 52.The

member 52 is moved slowly in or out lengthwise of the shaft 33,depending upon the direction of rotation of this shaft, and is providedwith a pair of longitudinally spaced tappets 56, 57 adapted to encounterthe lugs 58,59 of a whirling arm 60, the hub of which is fixed by ascrew 61 to the rotary shaft 33. The tappets 56, 57 are clamped to themem-' ber 52, so as to be relatively adjustable, and

are so set that when the car comes to the dumping position at the top ofthe body one of the tappets, for instance the tappet 57, comes into thepath of the lug 59 of the whirling member 60, which thereupon ives themember 52 a partial rotation, su cient to throw the reversible gear to aneutral position. Conversely, when the trough reaches the'lower end ofthe track, the other tappet 56 encounters the lug 58, which throws themember 52 in the opposite direction, thereby again bringing thereversible gear into neutral. A stationary pin 62 may be provided forsupporting the link bar 53 in the two extreme positions of the shifter,and the centers may be so arranged that the linkage will lock thereversible gear against unintended separation of the pinion 9 and thewheel 39, or the pinion 9 and the wheel 39, as the case may be. The bar53 may be extended beyond its connection with the lever 50, and may beprovided with a handle 63 for unlocking the linkage should occasionarise.

While the preferred form of the invention has been describedin detail,it will be understood that various changes may be made without departingfrom my invention.

For example :-The outstanding features of my refuse collector are theadaptation, as above described and shown, of an improved loading device,spoken of as a trough, to an.

improved cargo body, as a receiver, thus making for increased efliciencyand mmplicity of construction,and the equipment of the vehicle withimproved mechanism for operating the trough and cargo-body, thus makingfor increased steadiness and safety of operation. Changes in theadaptation or in the specific operating mechanism may be made withoutdeparting from my invention. so long'as the main features and resultsare obtained.

What I claim as new is:

l. A refuse collector comprising a chassis, a cargo body mounted on saidchassis having a curved top, and a receiving opening runningsubstantially the full length of the body, a protecting hood on thecurved top overhanging the opening and adapted to cooperate with aloading trough in its raised position so as to prevent escape ofdischarging material, a guide at each end of the opening having astraight portion along the side of the vehicle and a curved portionalong the curt'ed top co-operating with the protecting hood,a materialcarrying trough having a -material receiving opening substantially thelength of the body, guided along said guides and having a width so thatwhen raised it substantially fills said protecting hood, and means forraising and lowering said trough.
